Automated Helium Leak Testing for Large Coil Condensers

Boost Efficiency and Safety with VES Americas

Manufacturing large-coil condensers for HVAC systems demands the highest levels of precision, throughput, and safety. Traditional “sniffer”-style leak checks are manual, slow, and prone to variability especially when you’re dealing with lengths over 2 meters and hundreds of weld joints. At VES USA, we replaced that bottleneck with automated helium leak testing for large coils, delivering faster cycles, tighter control, and a 30% smaller factory footprint.

The Challenge of Large-Coil Leak Testing

Manual Variability: Sniffer probes detect at a single point and depend on operator skill.
Cycle-Time Drag: Walking a probe at 2 cm/sec around a 32-liter, 2 × 1.5 m coil could take hours.
Repeatability Issues: Ambient helium and human factors introduce false-positives or missed leaks.
Safety & Ergonomics: Vertical hanging tests expose operators to strain and potential hazards.

VES Americas’ Automated Solution

Dual Vacuum-Helium Test Chambers: Fully enclosed, two-station system that evacuates, pressurizes with helium tracer, and measures leaks with mass spectrometry—no manual sniffing required.
Process Automation: PLC-controlled load/unload conveyors and Schrader-valve actuators reduce human touchpoints to zero.
Data-Driven Control (VES Connect): Real-time metrics, pass/fail analytics, and preventative maintenance alerts ensure every coil meets spec and stay that way.
Modular, Scalable Design: From a single test cell to end-to-end production lines, our turnkey systems integrate seamlessly with existing conveyors, robots, or OP-10 data networks.

Tangible Benefits

>50% Cycle-Time Reduction: Faster vacuum pull-down and precise helium measurement cut testing time in half.
30% Footprint Savings: Vertical chamber design and stacked stations free up floor space for more production.
Consistent, High-Quality Output: Eliminates human error, so every weld, joint, and tube is verified under identical conditions.
Lower Operating Costs: Reduced helium consumption and labor hours translate to immediate OPEX gains.
Zero-Contact Safety: Operators handle only racks, not hazardous vacuum or tracer gas environments.
